The eGo-T has been getting questionable reviews over on ECF, a lot of the T owners have been switching over to that new GoGo kit which is apparently really badass.
As for me, I'm still on my regular eGo kit(650mAH). Next purchase is going to be the eGo mega kit(1100mAH), and possibly the MAP tank mod and some stuff for dripping. I've been ordering my juices from freedomsmokeusa...a little on the pricey side, but worth it so far. They use USP-certified PG and VG, and their nicotine is certified by a US lab which they haven't named from what I can tell. Juices are mixed in-house, my favorites so far are the 555 and the Thin Mint Cookie in 50/50 24mg. Mapvapes is another good supplier of juices from what I've read on ECF, prices look to be a lot cheaper than FSUSA.
OP, I have never seen or heard of your e-cig. You may be better off investing in a better kit like something from the Joyetech lineup...the 510 is dated, eGo is where its at. The eGo still uses the 510 threads, so you have an endless amount of carty/carto/tank/drip options, several battery options, various color options, plenty of accessories, etc. Generally, pre-filled carts either can't be refilled or are very hard to refill...but if you go with something like an eGo, you can get the boge cartomizers(atomized cartridge) which are easily refillable. I use the boge low-resistance cartos and love them.
ETA: Still haven't had a single analog since the day I got this kit in the mail, my only problem now is wanting to buy a bunch of different vaporizers and accessories.
